Vent plans
Prep for next vent
(1) Dichroic mirror replacements for PR3 and SR3
- quotes:
note: 2 deg wedge quote has Fused Silica grade F = 5 ppm homogeneity & micro roughness 0.3 nm RMS, Rana OKed both, 3 wks delivery, Jamie takes care of ordering
phase map of mirror, in and out of tip-tilt mounts
what resolution do we need? Need to measure curvature.
(2) IO Active tip-tilts (Suresh/Jamie)
Suresh is going to LHO April 15-25 for assembly/shipping of tip-tilts
- tip-tilts:
tip-tilts from LHO
bake
assemble
- add mirrors
- level
- in-vac cables (quadrapuses)
ship parts to RND Cables
place order with RND Cables
- bake
- electronics:
- gather components:
- DAC
- anti-image filters
- dewhite filters
- coil drivers
- eurocrate
- cables
- install
- test in DAQ
- gather components:
(3) Black glass beam dumps
- Large baffle style covers for the suspensions
- Small V-shape pieces for generic purpose
manufacture
- pedestals, clamps?
bake
- assemble
(4) OSEM mount screws
- requirements:
- Hex-top, longer, sliver-plated
- Qty = 100
- No-plastic
manufacture
bake
ready to install
(5) New periscope plate
manufacture
bake
ready to install
need shorter pedestals for green PBS and beam dump
(6) Cavity scattering measurements? (Jan)
(7) Review IP{ANG,POS} alignment/closeup proceedure
